Embodiment Construction

[0062] The illustrations in the figures are schematic. It should be noted that in different drawings, similar or identical elements are provided with the same reference signs, or reference signs differing from the corresponding reference signs only by the first digit. In order to avoid unnecessary repetition, elements or features which have already been explained with reference to the previously described exemplary embodiments are not explained again at a later point in the description.

[0063] figure 1 Shown is a block diagram of an RFID tag 100 comprising an electronic circuit chip 110 including a memory device with one-time read functionality. The RFID tag includes an electronic circuit chip 110 with a memory device 120 and an access circuit 140 for connecting the memory device 120 with components of the RFID tag not implemented in the electronic circuit chip 110 .

[0064] From figure 1 As can be seen, the memory device 120 includes a plurality of storage registers 122...

Abstract

It is described an electronic circuit chip for an RFID tag. The electronic circuit chip comprises (a) an access circuit configured for coupling the electronic circuit chip to an antenna element of the RFID tag, and (b) a memory device being connected to the access circuit. The memory device is configured for storing a secret value, for making retrievable the secret value, and for deleting the secret value. Deleting the secret value is accomplished if the secret value has been retrieved by means of a first attempt procedure for retrieving the stored secret value. It is further described an RFID tag comprising such an electronic circuit chip and a method for managing the use of a read-only-once secret value by an RFID tag with such an electronic circuit chip.

Description

technical field [0001] The invention relates to the field of electronic tags, in particular to the field of RFID technology. In particular, the present disclosure relates to electronic circuit chips for RFID tags, RFID tags provided with such electronic circuit chips, and methods for managing the use of secret values ​​stored in memory devices of such RFID tags. Background technique [0002] In many applications in everyday life, it is necessary to provide a ticket or label containing a secret value which can be read only once (one-time read secret value). Such tickets are currently used for example in lottery tickets, discount vouchers, gift cards, telephone calling cards and the like. [0003] A so-called scratch card coated with a layer of latex to hide the secret value printed on the card has been used. In order to make the secret value visible, the latex layer must be scratched away with eg a fingernail or a small hard object such as a coin. The latex layer both hold...
